This flotation step is conducted at alkaline pH. In the case where galena is floated and the copper minerals are depressed, copper depression can be achieved by using sodium sulphide, hydrosulfite, lime, cyanide, zinc-cyanide and/or ferricyanide complexes. Selection of flotation reagents and frothers is an important, even critical, consideration.
Sep 17, 2011 · The challenges in copper flotation that we came across during testing may be grouped as internal, species, and associated ganuge. Still we have not fully understood and each case is unique. Every project/program is a learning curve for me.
Metallurgical ContentThe Problem with separating Copper from Zinc by flotationThe Copper Zinc Process FlowsheetCRUSHINGROD MILLING The Problem with separating Copper from Zinc by flotation The treatment of heavy sulphide ores of copper containing zinc and pyrite is often extremely difficult particularly if soluble copper and sulphates are present.
At the end, the use of a sequential copper-lead-zinc flotation circuit produced the most efficient copper and lead separation. A bulk flotation process followed by a reverse flotation where copper was depressed and lead was floated from the bulk concentrate also produced separate concentrates, but at lower efficiency than the sequential circuit.

Dec 20, 2018 · Gold flotation. The Froth Flotation Method is means separating minerals according to their different physical and chemical properties. According to classification, the flotability of gold and silver minerals is included in the first category of natural and non-ferrous heavy metal sulfides, characterized by low surface wettability and easy flotation, which can be flotation by xanthate collectors.
Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
Various process chemicals are used in the froth-flotation of metallic ore of uranium, copper, zinc, lead, and iron. The flotation chemicals are mainly Isooctyl Acid Phosphate, Sodium Isopropyl Xanthate and Potassium Amyl Xanthate as conditioner and collector, MIBC as frothers, and sodium cyanide and copper sulfate as depressors.

Flotation is widely used to concentrate copper, lead, and zinc minerals, which commonly accompany one another in their ores. Many complex ore mixtures formerly of little value have become major sources of certain metals by means of the flotation process.
In this work, oxidizing roasting was combined with leaching to separate copper, lead, and zinc from a concentrate obtained by bulk flotation of a low-grade ore sourced from the Jiama mining area of Tibet. The flotation concentrate contained 7.79% Cu, 22.00% Pb, 4.81% Zn, 8.24% S, and 12.15% CaO; copper sulfide accounted for 76.97% of the copper, lead sulfide for 25.55% of the lead, and zinc ...

Arsenic minerals pose a problem for copper flotation concentrates since they are often associated with copper minerals, display similar flotation behaviour to copper minerals and therefore report to final copper flotation products. Despite extensive research, the rejection of arsenic minerals in copper flotation is still a challenge.
The tailing from the lead flotation circuit is the feed to the zinc circuit. The ability to selectively float the separate minerals depends on the ore, the chemicals, and other factors. Conclusion. Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even sand for glass are often processed by froth flotation.
